Determine the x-component of a vector in the xy-plane that has a y-component of -5.5 m so that the overall magnitude of the vector is 10.5 m. Assume that the vector is in Quadrant IV.

Multiply the 3 dimensions, assuming it is a rectangular cuboid, to get the volume in cm³ divide mass by volume to get density in g/cm³

The answer is -6hope this

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.

It would be c hope this out
